ChbB increases antifungal activity of Bacillus amyloliquefaciens against Valsa mali and shows synergistic action with bacterial chitinases

Apple Valsa canker (AVC), caused by the fungus Valsa mali (Vm), is a serious and persistent disease affecting apple production in China that is difficult to control chemically and agriculturally. In order to develop biological control agents (BCAs) for this disease, an antifungal activity-deficient Bacillus amyloliquefaciens mutant, ED-2544, was characterized using PCR amplification, Southern blotting, and SiteFinding-PCR. The B....
